Dev snapshot: Godot 3.2.2 beta 2
By: Rémi Verschelde May 07, 2020
After refining our Godot 3.2 release with bug fixes in 3.2.1, we're now looking at integrating some new features that didn't make it into the 3.2 merge window but have been further developed and backported since. We published a first beta a few weeks ago, and here's the next round with Godot 3.2.2 beta 2.
Notably, Godot 3.2.2 is going to add 5 major features:
- C# support for the iOS platform, courtesy of Ignacio (neikeq).
- 2D batching for the GLES2 renderer, thanks to lawnjelly and Clay (clayjohn).
- Several regressions and pre-existing GLES2 issues have additionally been fixed since 3.2.2 beta 1.
- Re-architecture of the Android plugin system, by Fredia (m4gr3d).
- DTLS support and ENET integration, developed by Fabio (Faless) (added in 3.2.2 beta 2).
- Fix for the dangling Variant bug, kudos to Pedro (RandomShaper) (added in 3.2.2 beta 2).
- While this is not a feature per se, it fixes a major annoyance that users have had with pointers to freed objects unexpectedly being re-assigned to new objects, causing hard-to-debug issues.
We need your help to test and validate these changes before publishing 3.2.2-stable, which is why we publish this beta build now. If you find any new issue with this build, especially related to one of the listed big changes, please report it on GitHub, ideally including a minimal project that can be used to reproduce the issue.
How to test
It should be safe to test this build directly with pre-existing projects made with Godot 3.2.x. It's of course always advised to use a version control system or backups in case you want to go back to the previous version (but testing 3.2.2-beta2 shouldn't prevent you from doing so anyway).
Note: If using C#, the
.csproj file will be converted with some bug fixes which makes it incompatible with earlier Godot 3.2 and 3.2.1. A backup of the file will be generated upon conversion so that you can revert to older releases if need be.
C# support for iOS
C# support for iOS should work similarly to exporting a GDScript project for iOS. Note that the export needs to be done from a macOS system to use the included AOT compiler for iOS arm64. If you run into any issue with the export process, please also test the export of a simple GDScript project to verify if the issue relates to the new C# support or to the iOS export pipeline in general.
GLES2 2D batching
The new 2D batching is only implemented for the GLES2 renderer, so if you use GLES3 you will not be able to benefit from it. As the GLES3 renderer is being deprecated by Vulkan in Godot 4.0, we currently don't plan to port the 2D batching to it. GLES2 batching is enabled by default both in-game and in the editor. You can turn it off or configure advanced settings in the Project Settings. Please see this dedicated issue for more details and to share your own testing results (we're interested in all feedback, whether you gained a lot of performance, lost some or didn't notice any chance). Note that currently, only rects are batched (TileMaps,
draw_rect, text rendering, etc.), but we plan to include more primitive types once this has been well tested.
New Android plugin system
Godot 3.2 came with a brand new Android plugin system already, and notably the possibility to build custom APKs from your project folder with any additional plugins/modules that your project needs.
Fredia had done a lot of work back then to improve Juan's initial custom build system, which led him to notice many things that could be modernized to be better suited to the current Android ecosystem. Notably, he re-architectured the plugin system to leverage the Android AAR library file format.
This new plugin system is backward-incompatible with the 3.2/3.2.1 system, but both systems are kept functional in future releases of the 3.2.x branch. Since we previously did not version our Android plugin systems, this new one is now labelled
v1, and is the starting point for the modern Godot Android ecosystem.
DTLS support and ENet integration
Fabio's work on DTLS support was nearly done by the time 3.2 was released, but came too late to be thoroughly tested. Testing has happened since then both in the
master branch and in the pending
3.2 Pull Request, so we're now confident to include it in this beta build for further testing.
See the dedicated devblog for usage examples.
Fix for the dangling Variant bug
If you were running into this bug, it would typically be in situations where you'd check
is_instance_valid() on what you expect to be a freed instance (which should give
False), and it would actually return
True and lead you to access a method or a property of a different object (causing an error if the object's class does not include this method or property).
The fix made in the 3.2 is only done on debug builds for performance reasons, so make sure to fix any error reported by the editor or debug builds before shipping a release build to your players. In the upcoming Godot 4.0, this bug was fixed with a more comprehensive approach which prevents dangling Variant pointers in both release and debug builds.

The download links for dev snapshots are not featured on the Download page to avoid confusion for new users. Instead, browse our download repository and fetch the editor binary that matches your platform:
- Classical build (GDScript, GDNative, VisualScript).
- Mono build (C# support + all the above). You need to have MSBuild (and on Windows .NET Framework 4.7) installed to use the Mono build. Relevant parts of Mono 184.108.40.206 are included in this build.
As a tester, you are encouraged to open bug reports if you experience issues with 3.2.2 beta 2. Please check first the existing issues on GitHub, using the search function with relevant keywords, to ensure that the bug you experience is not known already.
In particular, any change that would cause a regression in your projects is very important to report (e.g. if something that worked fine in 3.2.1 no longer works in 3.2.2 beta 2).
